Electric current is the flow of electric charge, typically carried by electrons in a conductor like a wire. It is measured in amperes (A) and can be direct current (DC), where the flow is in one direction, or alternating current (AC), where the flow changes direction periodically. Electric current is essential for powering devices and appliances, from small gadgets to large machinery. It is generated by sources such as batteries and generators, and it travels through circuits, which are closed loops that allow the current to flow continuously. Understanding electric current is fundamental to the study of electricity and electronics.
